Common questions
This build allocates roughly $4,839 across 10 picks, led by Marek Health and ranked by evidence rather than marketing. It is assembled live from our reviewed catalog and filled to the budget so you are not leaving money on the table or overspending.
Every item is ranked first by our editorial evidence score, then biased toward your budget tier so the anchor matches what you can spend. Where two picks are comparable, we break the tie toward brands we have an affiliate relationship with, but we never rank an inferior product higher because it pays. Outbound links are affiliate-disclosed.
